Demons

The famous knight Apoc once wrote:

"Demons are the most malevolent, powerful, and dangerous creatures in Tibia. In addition to their awesome physical strength, they can also use powerful spells, such as fireballs and fire fields. Especially dangerous is their gaze, which can produce beams of pure energy to annihilate their poor victims. Moreover, they drain mana off their victims, heal themselves and summon fire elementals as their vassals.
Fortunately, Demons usually live in the deepest dungeons near hell but sometimes they appear also on the surface. When they do, they leave a track of death and destruction behind them. Nobody has ever been able to slay even one of these entities and only very few adventurers have survived an encounter with them."

Demons have 8200 hitpoints. They are immune to fire damage and cannot be paralyzed. Moreover, they are strong against physical, earth, energy, and death damage. On the other hand, they are weak against ice and holy damage. These creatures can neither be summoned nor convinced. In addition, they are able to sense invisible creatures.

Demons yield 6000 experience points. They carry gold coins, great mana potions, platinum coins, ultimate health potions, double axes, fire mushrooms, small emeralds, and sometimes other items with them.
